The development of novel aquaculture operations requires extensive information on the local environment, infrastructure, and available support services. Compiling and sorting this information is an important prerequisite for supporting sound regulatory and business decision making. Despite the availability of various high-quality applicable data, the large quantity and disparate sources of different data sets requires extensive effort to collect and evaluate in a coherent manner. To help address this problem the Centre for Marine Applied Research partnered with the Atlantic Canada Opportunities Agency and provincial departments to create a single-GIS platform that shows important infrastructure, environmental data and services to support aquaculture development in Nova Scotia. An online interactive GIS map was developed in an ArcGIS Platform and posted on the CMAR website. Over fifty spatial layers make available a wide range of spatial data important to net-pen, shellfish and land-based aquaculture. This presentation reviews the tool functionality, available data layers and examples of how this tool can support pragmatic decision making for aquaculture.
